Process for the manufacture of transparent papers, particularly those used for the packing of edible articles



Patented Dec. 30, 1930 OTTO KLOTZ, F GOPPINGEN, GERMANY PROCESS FOR THEMANUFACTURE OF TRANSPARENT PAPERS, PARTICULARLY THOSE USED FOR THEPACKING OF EDIBLE ARTICLES No Drawing. Application filed February 25,192?, Serial No. 171,071, and in Germany October 9, 1926.

The present invention relates to a process for the manufacture oftransparent papers, which are intended in particular for bags and otherpackings for edible articles and eat-ables. The paper which has hithertobeen used for these purposes is transparent to a certain extent only,such, for example, as parchment, pergamyn, Waxed paper, oiled paper,etc. This transparency is however so slight that articles packed thereincan only advantage such as pergamyn, parchment etc.

but the process is characterized by the fact that such papers of otherkinds, e. g. tissue paper can be used for the said purpose.

The process is very simple to carry out and consists in applying acoating of gelatine to the paper which after drying becomes transparent.According to the degree of transparency required the gelatine solutionis applied on one or both sides. The thickness of the coating and themanner in which it is applied may be any that is desired. Instead ofgelatine other colloidally acting substances may be used. I claim Aprocess for producing a transparent paper particularly for packingedibles, which 0 comprises in coating the outside of both sides of atranslucent paper with a solution of gelatine to render it transparent.

In testimony whereof I aflix my signature.

OTTO KLOTZ.
